Accord's GPSLAB is a PC based GPS software simulator which can simulate GPS satellite constellations and GPS receiver sensor. GPSLAB supports simulation of user's vehicle motion in real time and models the behavior of a GPS receiver.

PC Clock synchronization using GPS. It can be used as NMEA and COM port tester. The program synchronizes a PC Clock to the right time using artificial satellites. It is a PC Clock synchronization program. It is alternative solution to synchronizing with atomic clock using NTP(SNTP) and Internet.

GPS component VB library toolkit reads and decodes standard GPS NMEA 183 sentences from the RS232 serial port, as well as computes great circle distances and bearings. Runs as a background thread unattended. Works with Visual Basic and VB.NET.

GPS Express provides a feature rich interface to serial NMEA-0183 protocol data and works with most NMEA-0183 devices, including GPS Receivers. GPS Express is available in three versions (Standard, Professional, Graphical)...

Toolkit to add GPS functionality to software. All NMEA0183 protocol versions are supported, all NMEA 0183 can be filtered by NMEA type and talker ID. Values can be outputed using different output formats and units.
